Per NBC, Diaz's fourth 'SNL' hosting gig will be flanked by Bruno Mars and Mark Ronson, performing together for their collaboration on Ronson’s upcoming single “Uptown Funk.” Given Diaz's musical role in the live-action 'Annie' update, we wouldn't rule out a bit of singing on her part, either.

Diaz has made multiple appearances on the long-running NBC sketch comedy series, hosting in 1998, 2002 and 2005, as well as introducing then-boyfriend Justin Timberlake’s musical performance in 2006. Mars also hosted and acted as the musical guest in 2012, so hopefully we might see the performer engage in a bit of crossover this time around as well.
